Abstract

There are described a method for applying a coating to a surface of an ophthalmic lens mold. The mold comprises male and female (20) mold halves, with each of the mold halves being provided with a lens forming surface (21). The method includes - applying a temporary coating to at least a portion of at least one of the male and female mold halves (20), the temporary coating being capable of reducing adhesive forces between a lens forming material and the lens forming surface (21); and - drying the temporary coating applied to the portion of the lens forming surface (21). Also described is a device (1) for applying such temporary coating to the portion of the lens forming surface (21) of the ophthalmic lens mold.
